Description

FIELD OF INVENTION

This invention relates generally to a consumer-type refrigerator, and more particularly to a refrigerator with a universal crisper frame able to accommodate a variety of crisper configurations.

BACKGROUND OF THE INVENTION

Consumer refrigerators such as might be found in a household typically include a fresh food compartment. The refrigerator is provided with an evaporator for maintaining the fresh food compartments at a temperature range of about 32-40 degrees Fahrenheit. However, it is desirable to create separate compartments within the fresh food compartment. These compartments are commonly known as crisper drawers and can be kept at a different temperate and/or humidity than the fresh food compartment to accommodate the storage requirements for certain food items, such as dairy products, meats, fruits, and vegetables. Crisper drawers are internal drawers which can only be accessed if the fresh food compartment door is already open. Some refrigerators include a full width pantry or crisper drawer which is also an internal storage compartment which can only be accessed if the fresh food compartment door is already open. What is needed is a refrigerator and a method of manufacturing a refrigerator which allows different configurations of crispers.

The perimeter frame 18 may also be adapted to support a shelf. The exemplary embodiment of FIG. 2 further shows a refrigerator drawer body 30 with a bottom and plurality of upright walls operatively connected to the bottom. In first exemplary embodiment of FIG. 2, the refrigerator drawer body 30 is a full width drawer body, that is, the drawer body is approximately the full width of the perimeter frame 18. A second exemplary embodiment is shown in FIG. 2 wherein the refrigerator drawer body 30 is a half width drawer body with a bottom and a plurality of upright walls operatively connected to the bottom. In this embodiment, the refrigerator drawer body 30 is approximately half the width of the perimeter frame. Moreover, perimeter frame 18 and refrigerator drawer body 30 can be configured to move relative to perimeter frame 18 using a variety of subassemblies such gliding, sliding or rolling. As will be discussed below, and as can be appreciated by a skilled artisan, the present invention contemplates configuring a plurality of refrigerator drawer bodies of varying widths to move in several distinct ways to accommodate fresh food storage needs without substantially altering the refrigerator drawer assembly 10.

Now with reference to FIGS. 3-5A, a first exemplary embodiment of the present invention is shown. In this embodiment, refrigerator drawer assembly 10 utilizes a full width refrigerator drawer body 30. Support member 40 is in a second position and thus is not connected to the perimeter frame 18 at snap receivers 19 and 20. In FIG. 3, a perimeter frame 18 is shown configured to receive a full width refrigerator drawer body 30 and allow movement using a sliding refrigerator door subassembly 80. With this arrangement, the drawer body 30 is slidably supported by the perimeter frame 18 relative to front portion 21 and rear portion 22. As best shown in FIG. 3A, a channel 70 is disposed on side portion 23 and side portion 24 (not shown) to slidably receive the drawer body 30. The sliding subassembly 80 as shown will allow for plastic-on-plastic movement of the drawer body 30 with the perimeter frame 18. Moving to FIG. 4, perimeter frame 18 is configured to allow a full width refrigerator drawer body 30 to move using a rolling refrigerator door subassembly 90. With this arrangement, rollers 50 are connected to perimeter frame 18 at mount 28 and mounts disposed drawer body 30 (not shown) to rollably support the drawer body 30. As best show in FIG. 4A, rollers 50 are mounted to the perimeter frame 18 at mount 28. Thus, when inserted the drawer body 30 contacts the roller 50 and is received into channel 70. When the drawer body is withdrawn, a roller at mount 28 support a forward portion of the drawer body 30 while rollers mounted on the drawer body 30 (not shown) support a rearward portion of the drawer body 30. The combination of rollers 50 mounted on the perimeter frame 18 and drawer body 30 provide a continued rolling support when the drawer body 30 is both inserted and withdrawn.

With respect to FIG. 5, perimeter frame 18 is configured to allow a full width refrigerator drawer body 30 to move using a gliding refrigerator door subassembly 100. With this arrangement, a standard under-the-drawer style gliding system is used to allow for movement of the drawer body 30 relative to the perimeter frame 18. The gliding subassembly 100 allows the drawer body 30 to be withdrawn entirely from the refrigerator 1 while still being supported by perimeter frame 18. As best shown in FIG. 5A, glide 60 may be mounted to the perimeter frame 18 with screws (not shown) or glide 60 may be snapped into the perimeter frame 18. An adaptor 62 is added to the glide 60 such that the drawer body can be mounted at the same level it would be if used the aforementioned sliding or rolling subassemblies. In this manner, the same drawer body can be used in each of the sliding, rolling, or gliding subassemblies.

As shown in FIGS. 6A and 6B, support member 40 has a snap 46 on first end 47 and second end 48. In operation, a user snaps first end 47 and second end 48 of the support member 40 to a front snap receiver 19 and a rear snap receiver 20 disposed on the perimeter frame 18. As best shown in FIGS. 3A and 6B, a channel 70 is disposed on side portion 23 and 24 (not shown) of the perimeter frame 18 and on walls 42 of support member 40. With this arrangement, the drawer body 30 is slidably supported by the perimeter frame 18 and support member 40 to move relative to front portion 21 and rear portion 22 of the perimeter frame 18. The sliding subassembly 80 as shown will allow for plastic-on-plastic movement of the drawer body 30 with perimeter frame 18 and support member 40. Moving now to FIG. 7, perimeter frame 18 and support member 40 are configured to allow a half width refrigerator drawer body 30 to move using a rolling refrigerator door subassembly 90. As best show in FIGS. 4A and 7A, rollers 50 are mounted to the perimeter frame 18 at mount 28 and support member 40 at mount 44. With this arrangement, rollers 50 are connected to perimeter frame 18, support member 40, and drawer body 30 (not shown) to rollably supported the drawer body 30. Thus, when inserted the drawer body 30 contacts rollers 50 and is received into channel 70. When the drawer body is withdrawn, rollers at mount 28 and mount 44 support a forward portion of the drawer body 30 while rollers mounted on the drawer body 30 (not shown) support a rearward portion of the drawer body 30. The combination of rollers 50 mounted on the perimeter frame 18, support member 40 and drawer body 30 provide a continued rolling support when the drawer body 30 is both inserted and withdrawn.

With respect to FIG. 8, perimeter frame 18 and support member 40 are configured to allow a full width refrigerator drawer body 30 to move using a gliding refrigerator door subassembly 100. With this arrangement, a standard under-the-drawer style gliding system is used to allow for movement of the drawer body 30 relative to the perimeter frame 18. The gliding subassembly 100 allows the drawer body 30 to be withdrawn entirely from the refrigerator 1 while still being supported by perimeter frame 18 and support member 40. As shown in FIG. 8A, a support member is provided to which a glide 60 may be snapped into or mounted to with screws (not shown). An adaptor 62 is further added to the support member 40 and glide 60 such that the drawer body can be mounted at the same level it would be if used the aforementioned sliding or rolling subassembly. In this manner, the same drawer body can be used in each of the sliding, rolling, or gliding subassemblies.
